[0002] As people's living standards continue to improve, the requirements and types of edible oils are diverse. Among them, peanut oil is one of the healthy oils recommended by the World Health Organization. Peanut oil is rich in lipid active ingredients such as phytosterols and vitamins. Peanut oil is rich in various fatty acids and various trace elements such as zinc and vitamin E, resveratrol and other alcohols. In the production and processing of peanut oil, it is necessary to use oil pressing equipment to press the peanut raw materials.

[0003] Before the peanut raw materials are processed for oil extraction, they need to be stir-fried and crushed for pre-treatment. However, the existing peanut oil extraction device cannot perform convenient and efficient integrated oil extraction processing on the peanut raw materials in actual working process. Therefore, it is necessary to use multiple devices to gradually process the peanut raw materials, which has poor practicality and low working efficiency. Moreover, after the peanut raw materials are processed for oil extraction, a certain amount of oil still remains in the remaining residue which has not been extracted completely, and the oil yield is low, resulting in a waste of raw materials. In actual working process, the existing peanut oil extraction device cannot further extract the oil remaining in the residue, resulting in a low oil yield of the peanut raw materials, thereby resulting in high cost.

The driven shafts on both sides can drive the second rotating cylinder to rotate stably in the crushing tank during the revolution and rotation. Combined with the first crushing blades and the second crushing blades, the stir-fried peanuts can be automatically crushed and crushed into smaller particles, which helps to destroy the cell wall, release more oil, and improve the oil yield. Similarly, after the peanuts are hydraulically pressed, the first processing cylinder and the second processing cylinder are turned over 180 degrees again. At this time, the residue after oil pressing can be transported to the crushing tank again, and then the automatic crushing of the oil pressing residue can be automatically completed, and its surface area is increased, thereby increasing the contact area between the residue and the solvent, and ensuring the efficiency of subsequent leaching.

After the first treatment cylinder and the second treatment cylinder are flipped 180 degrees, the oil pressing residue can be automatically pushed into the guide cylinder under the movement of the extrusion plate and the guide plate, ensuring the convenience and efficiency of the subsequent leaching of the residue.

[0060] It should be noted that the present invention is a device and process for improving the oil extraction rate of peanuts. First, the staff can lift up the magnetic cover plates 21 on the loading funnels 20 on both sides of the second processing cylinder 5, and then the staff can transport the peanuts to be used into the loading funnel 20. The peanuts can be transported into the second processing cylinder 5 through the loading funnel 20. Then the staff can turn on the electric heating tubes 817 in the second processing cylinder 5 and the servo motor 801 at the bottom. Under the driving action of the servo motor 801, the positioning frame 802 can be driven to rotate through the output shaft, and the positioning block 803 can be driven to rotate synchronously through the positioning frame 802, thereby driving the driving shaft 804 to rotate synchronously. The driving shaft 804 is in motion. At this time, under the rotation of the driving shaft 804, the connecting plate 901 and the first rotating cylinder 902 can be driven to stably rotate in the first processing cylinder 3. During the rotation of the connecting plate 901, the driven shafts 808 on both sides can be driven to perform circular motion, that is, revolution. During the revolution of the driven shafts 808 on both sides, the second circular gear 911 on the top can be driven to perform circular motion on the internal gear 910 in the protective frame 909. At this time, during the revolution of the second circular gears 911 on both sides, the second circular gears 911 in the revolution process can be driven to automatically rotate by meshing with the internal gear 910, thereby driving the driven shafts 808 on both sides to automatically rotate during the revolution.

[0061] During the movement of the driven shafts 808 on both sides, the sliding plate 809 at the bottom can drive the sleeve 811 to move synchronously, and during the rotation of the sleeve 811, the connecting plate 815 at the bottom can drive the upper top block 816 to move in a circular motion. At this time, the upper top block 816 can intermittently contact the lower top block 807 on the scraper rod 806. When the upper top block 816 and the lower top block 807 are in contact, the lower top block 807 can push the sleeve 811 on the upper top block 816 to move upward. When the upper top block 816 and the lower top block 807 are separated, the sleeve 811 can be driven to move downward and reset under the elastic action of the connecting spring 810, and so on. During the revolution and rotation, the rotary drum 802 can also automatically and stably reciprocate up and down, and during the rotation of the positioning frame 802, the scraper rods 806 on both sides can be driven to rotate synchronously. At this time, the spiral blades 814 on the sleeves 811 on both sides, combined with the stirring rods 805 on the driving shaft 804 and the scraper rods 806 and the electric heating tube 817 in the second processing barrel 5, can be used to conveniently and efficiently stir and fry the peanut raw materials in the second processing barrel 5 in all directions. Stir-frying can destroy the internal cells of the peanuts, denature the protein, aggregate the fat, and reduce the viscosity and surface tension of the fat, so as to ensure that the fat can be fully produced later and improve the oil yield;

[0062] The waste gas generated during the peanut frying process can be transported to the fixed frame 11 through the first material guide trough 907, the crushing trough 903, the second material guide trough 908 and the material guide cylinder 10, and then filtered and purified through the filter plate 12 and the activated carbon mesh plate 14 on the magnetic frame 13 to avoid air pollution. After the peanut frying process, the staff can drive the first hydraulic rod 205 on both sides. Under the driving action of the first hydraulic rod 205, the first processing cylinder 3 can be driven to move upward through the rotating shaft 207 on the fixed block 206, and then the second processing cylinder 5 can be driven to move synchronously. At this time, during the movement of the rotating shaft 207, the limit plate 208 can be driven to slide in the second limit groove 203 on the fixed plate 201, and the first circular gear 209 can be driven to move upward in the first limit groove 202 in the fixed plate 201. When the first circular gear 209 moves to contact with the rack 204, the limit plates 208 on both sides move to the second limit The second limiting groove 203 does not limit the limiting plate 208 at this time, so under the movement of the first circular gear 209, it can mesh with the rack 204, and then the first circular gear 209 can drive the rotating shaft 207 to rotate automatically, thereby driving the first processing cylinder 3 and the second processing cylinder 5 to rotate automatically. Since half of the circumference of the first circular gear 209 is equal to the length of the rack 204, the first circular gear 209 can drive the first circular gear 209 to rotate 180° when meshing with the rack 204. After the first circular gear 209 rotates 180°, the limiting plates 208 on both sides move to the upper part of the second limiting groove 203. At this time, the second limiting groove 203 continues to limit the limiting plate 208, so that the 180° flip of the first processing cylinder 3 and the second processing cylinder 5 can be completed conveniently, and it is in a limited state, ensuring the stability of the subsequent working state of the first processing cylinder 3 and the second processing cylinder 5.

[0063] After the first processing drum 3 and the second processing drum 5 are turned over, the stir-fried peanuts can automatically fall to the first material guide groove 907 on the first rotating drum 902 under the action of their own gravity. At the same time, the first rotating drum 902 is still in a rotating state. At this time, under the continuous rotation of the first rotating drum 902, the second pushing rod 913 made of rubber can push the remaining peanuts to the first material guide grooves 907 on both sides. At this time, the stir-fried peanuts can automatically enter the first material guide grooves 907 on both sides. At this time, under the guidance of the first material guide grooves 907, the peanuts can automatically enter the crushing grooves 903. At the same time, since the driven shaft 808 automatically rotates during the revolution, but the first rotating drum 902 is also in a rotating state, the crushing grooves 903 on both sides of the first rotating drum 902 also revolve synchronously. At this time, the driven shafts 808 on both sides can drive the second rotating drum 904 to be stable in the corresponding crushing grooves 903 The second rotating cylinder 904 rotates stably. Under the continuous rotation of the second rotating cylinder 904, the first crushing blades 905 on the second rotating cylinder 904 and the first crushing blades 905 in the crushing groove 903 can be used to automatically coarsely crush the peanuts. Then the peanuts continue to fall to the second crushing blades 906. Similarly, the second crushing blades 906 on the second rotating cylinder 904 and the second crushing blades 906 in the crushing groove 903 can be used to automatically finely crush the peanuts. The finely crushed peanut raw materials can automatically move to the connecting plate 901 through the second material guide groove 908. At the same time, under the rotation of the driven shaft 808, the first push rods 912 can be driven to rotate synchronously, so that the finely crushed peanut raw materials can be automatically moved to the guide cylinder 10. At this time, the finely crushed peanut raw materials can be automatically transported to the fixed frame 11 through the guide cylinder 10.

[0064] After all the peanuts are crushed, they are all transported to the fixed frame 11. Then the staff needs to pull the magnetic frame 13 away from the fixed frame 11 to complete the disassembly of the activated carbon screen plate 14, so as to facilitate the subsequent replacement and processing. Then the staff needs to place the collection frame 19 in the limit frame 18 for limit placement. Then the staff can drive the second hydraulic rods 15 on both sides of the fixed frame 11. Under the driving action of the second hydraulic rods 15 on both sides, the corresponding squeezing plates 16 can be driven to move toward the middle at the same time, so that hydraulic oil pressing can be performed. At this time, the squeezed peanut oil drips through the filter screen plate 12 into the collection frame 19 for automatic collection.

[0065] After the hydraulic oil pressing work is completed, the staff can lift up the collection frame 19 and take it away, and then drive the first hydraulic rods 205 on both sides. Under the driving action of the first hydraulic rods 205, the rotating shaft 207 on the fixed block 206 can drive the first processing cylinder 3 to move downward and reset, and then drive the second processing cylinder 5 to move synchronously. Similarly, under the downward movement of the first processing cylinder 3 and the second processing cylinder 5, the first circular gear 209 can be driven to mesh with the rack 204 again. At this time, the meshing drive rotates in the opposite direction. , but the rotation angle is the same, still rotating 180°, at this time, the first processing cylinder 3 and the second processing cylinder 5 are reversely turned 180° to complete the reset work. After the first processing cylinder 3 and the second processing cylinder 5 are turned and reset, the residues left after oil pressing can be transported to the second material guide groove 908 on the first rotating cylinder 902 again through the material guide cylinder 10 under the action of its own gravity, and under the inclined material guide action of the material guide plate 17 at the bottom of the squeezing plate 16 on both sides, all the residues can be pushed to the second material guide groove 908 on the first rotating cylinder 902;

[0066] Similarly, under the continuous rotation of the second rotating cylinders 904 on both sides, the residue can pass through the first crushing blade 905 and the second crushing blade 906 again. At this time, after the residue is coarsely crushed and finely crushed, it can be automatically transported to the second processing cylinder 5 through the first guide groove 907; then, the staff can use the feeding funnel 20 again to transport the leaching solvent into the second processing cylinder 5. Similarly, at this time, the spiral blades 814 on the sleeves 811 on both sides of the second processing cylinder 5, combined with the stirring rods 805 on the driving shaft 804 and the scraper rod 806 and the electric heating tube 817 in the second processing cylinder 5, can be used to efficiently and evenly mix the oil pressing residue and the leaching solvent in the second processing cylinder 5, thereby improving the leaching efficiency and further improving the oil yield;

[0067] After the oil pressing residue and the leaching solvent are uniformly mixed, they are left to stand. At this time, the oil and the solvent are naturally separated into layers. According to the difference in density, the oil will float on the top and the solvent will sink to the bottom. When the mixture is separated into layers, the solenoid valve on the discharge pipe 22 on one side is opened to discharge the solvent below and retain the oil on the upper layer. Then, the solenoid valve on the discharge pipe 22 on one side is closed, and the solenoid valve on the discharge pipe 22 on the other side is opened to discharge and collect the oil that saves oil;

[0068] After the device is finished working, two staff members can pull the clamping rod 7 on the second treatment cylinder 5 outward until the clamping rod 7 moves out of the clamping slot 4 on the first treatment cylinder 3, and then the second treatment cylinder 5 can be easily disassembled. At this time, the positioning frame 802 and the positioning block 803 are separated, which is convenient for cleaning the residual leaching solvent inside the second treatment cylinder 5. After the cleaning work is completed, the second treatment cylinder 5 can be again mounted on the first treatment cylinder 3, and the positioning frame 802 and the positioning block 803 must be engaged. Before mounting, it is necessary to pull the clamping rod 7 on the second treatment cylinder 5 outward in advance. After the second treatment cylinder 5 is mounted on the first treatment cylinder 3, the staff can release the clamping rod 7. At this time, under the elastic action of the reset spring 6, the clamping rod 7 can be driven to automatically engage with the clamping slot 4 on the first treatment cylinder 3, completing the clamping installation of the second treatment cylinder 5 and ensuring the stability of its subsequent working state.
